I have a question, I have a b20b, boosted, wiseco pistons 8:5:1 compression, eagle rods, acl race bearings. I am tuned at 8 psi right now with 250 to the wheels. I have been told many different numbers about what my block can handle, I know it has a lot to do with tunning,and I know the cylinder walls are a little thin, just need to know an accurate number so I can set my high boost tune, safely, thanks in advance

 

there is no accurate number. this depends upon turbo, injector and tuner.
